SOAP-DISPENSER.

Application filed May 15, 1917.

To all whom it may concern:

.Be it known that I, DON L. KIMBALL, a subject of Gt. Britain, residing at Portland, in the county of Multnomah and State of Oregon, have invented certain new and useful Improvements in Soa -Dispensers; and I do hereby declare the fo lowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a soap dispenser and more particularly to one designed for dispensing-soap in the form of paste or cream.

The principal object of the invention is to provide a soap dispenser of the above stated character which may be readily and quickly operated successively to dispense predetermined quantities of soap paste, suitable means being provided within the device, adapted upon actuation to create a suction force upon the mass of soap within the container sufiicient-to break or cut off the paste at the discharge orifice and at the same time tending to draw in and prevent the soap from further escaping.

. Another object of the invention is to provide a soap dispenser in which is mounted a reciprocal plunger rod having a piston adjustably mounted thereon and normally resting upon the mass of soap within the container, whereupon after reciprocation of the plunger rod, the piston will successively compress and release the compression of the soap, the releasing of the compression creating a suction force sufficient to stop a further dispensation of the soap.

A further object of the invention is to provide a soap dispenser in which is removably positioned a reciprocal plunger having a piston adjustably mounted thereon, the plunger rod and piston being reversible end for end within the device.

A still further object of the invention is to provide a soap dispenser of the above stated character which will be of comparatively cheap and inexpensive construction, one which can-be quickly and readily filled within a minimum amount of time and labor.

With these and other objects in view as will appear as the description proceeds, the invention comprises the various novel features of construction, combination and arrangem'ent of parts as will be more fully dc.

scribed hereinafter and set forth with particularity in the appended claim.

Referring more particularly to the drawings,

Figure l is a top plan view of my novel construction of soap dispenser.

Flg. 2 is a top plan view of the device with the cover removed.

Fig. 3 is a bottom plan view of the cover.

Fig. 4 is a side elevation of the actuating handle and ratchet disk attached to the stem thereof.

Fig. 5 is a transverse sectional view taken on the line 55 of Fig. 4.

Fig. 6 is a vertical sectional. on the line 66 of Fig. 1, and

Fig. 7 is a bottom plan view of the soap dispenser.

Similar characters of reference are used to denote corresponding parts throughout the accompanying drawings and the following description.

Referring to the drawings, the numeral 1 represents a cylindrical container having its lower end conical shaped as indicated by the numeral 2, and the extreme lower end of it provided with a discharge orifice 3.

The upper end of the container is adapted to be closed by. a-cover-4l that is provided internally with lugs 5 that are adapted to engage bayonet slots 6 to hold and maintain the cover in position. The cover 4 is provided centrally with an aperture 7 through which is disposed the stem 8 of the actuating handle 9, and threadedly connected to the inner end of the stem 8 is a ratchet disk 10 which is'adapted to engage and cooperate with a ratchet disk 11 carried by the inner surface of the top of the cover 4. In order to maintain the teeth of the ratchet disk 10 in engagement with those of the ratchet disk 11 an expansible coil spring 12 is positioned around the stem 8 between the handle 9 and the top of the cover 4:, and this expansible spring is inclosed within a sleeve 13 resting upon the cover 4. The top of the handle is provided centrally with a button 14 that is adapted to contain suitable indicia to indicate the direction of rotation of the handle.

The inner end of the stem 8 is .provided centrally with a non-circular tapering opening 15 that is adapted to receive either of the non circular ta ering ends 16' of a threaded. plunger ro' 17: I

view taken Patented Aug. 12, 1919.

This plunger rod 17 has adj ustably mounted thereon a piston 18 and designed to normally rest upon the mass of soap within the container. This piston 18 consists of a piston head 19, which is preferably constructed of rubber or leather, and is positioned between a pair of metal disks 20. A flanged bushing 21 is positioned centrally through the disks 20 and the head 19 and is provided with a nut 22 whereby said parts may be clamped together. The bushing is internally threaded and adapted to automati- Cally feed downwardly upon the plunger rod 17 as it is successively actuating in dispensing the soap; 7

The container 1 may be supported in any suitable manner but for the purpose of illustration, I have shown a. bracket arm 23 which extends horizontally from the container and is provided with a flange 24: at its outer end that is adapted to be rigidly attached to a suitable support through the medium of screws 25.

In the operation of the device and assuming that the piston 18 is resting upon the mass of soap within the container, the handle 9 is turned to the right until the ratchet disk 10 has been moved a quarter turn, which movement will be sutficient to dispense a predetermined quantity of the paste soap from the discharge orifice 3. In turning the handle 9 the stem 8 carrying the ratchet disk 10 will move downwardly the depth of the ratchet teeth of the disk 11, and at the same time move the plunger rod 17 downwardly an equal distance. As soon as the handle 9 has been turned a quarter turn or far enough for the ratchet teeth of the disk 10 to ride over those of the ratchet disk 11, the expansion spring 12 will automatically move the stem 8 upwardly and the teeth of the two ratchet disks into interlocking engagement with each other. At the same time that the handle 9 is rotated a quarter turn, the piston 18 will be moved downwardly a predetermined distance upon the mass of soap so as to slightly compress it at the same time that the plunger rod is moved downwardly. This compression of the soap together with the downward movement of the plunger will facilitate an easy and ready dispensation of a predetermined amount of soap paste. After each successive dispensation of soap, the spring 12 will move the stem 8, plunger rod 17 and its respective piston 18 upwardly, and this upward movement of the piston 18 will be suificient to create a suction upon the mass of soap great enough to stop the discharge of the soap from the orifice 3 and at the same time tend to draw the soap within the orifice inwardly. This suction created by the upward movement of the piston 18 Copies o'fthis patent may be obtained for will therefore be sufficient to act upon the soap paste to prevent any further discharge or leakage of it after each dispensation.

By successfully operating the soap dispenser, the piston 18 will gradually and automatically ride dowmva-rdly upon the plunger rod 18 until it has reached the lower conical end of the container or the limit of its downward movement. \Vhen the piston 18 has reached the limit of its downward movement it will be impossible to rotate the han-' dle 9 in either direction by virtue of the po sition of the piston and the ratchet teeth of the disks 10 and 11.

When the handle 9 can not'be rotated any further it will indicate that the container needs refilling, and to accomplish this the cover 4: is removed together with the plunger rod 17 and the piston 18 carried thereby. After removing the plunger rod 17 and the piston carried thereby, the plunger rod is detached from the stem 8 and reversed end for end so that after the container has been refilled with soap paste the piston 18 will be in a position to rest upon the mass of soap that has been positioned within the container without the necessity of screwing the piston back upon the plunger rod to its original position. This will save considerable time and labor in refilling the device. It is of course to be understood that the tapered ends 16 are adapted to fit sufficiently tight within the opening 15 to prevent their disengagement upon the expansion of the spring 12 and the upward movement of the stem 8 or on the other hand the suction resistance of the piston 18 will not be great enough to dislodge the plunger rod from its connection with the stem 8.

I claim,

A soap dispenser comprising a container having a discharge orifice in its lower end, a cover for said container, a handle having a stem disposed centrally through said cover, said stem being provided in its inner end with a noircircular socket, a removable ratchet disk carried by the inner end of said stem, a ratchet disk carried by the inner surface of said cover and adapted to engage the ratchet teeth on said stem, a coil spring positioned around said stem between the handle and the cover and adapted to normally maintain said ratchet disks in interlocking engagement with each other, an invertible threaded plunger rod having is opposit-e ends of non-circular formation and adapted to be selectively engaged within said handle stem socket, and a piston head adjustably mounted on said plunger rod.

In testimony whereof I have signed my name to this specification.
